Parietal lobe which is responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness. Occipital lobe which is responsible for processing information related to vision. Cerebrum lobe which is the biggest part of the Brain, its role is memory, attention, thought, and our consciousness, senses and movement. Lastly there is Hippocampus which is responsible for memory forming, organizing and storing and emotions. 1.3 -Explain why depression, delirium and age-related memory impairment may be mistaken for dementia This may be the case because they all share many of the same symptoms as dementia, for example depression can manifest as anxiety, irritability, sleep disturbance, changes in appetite, weight loss or occasionally weight gain, fatigue, decreased energy and difficulty concentrating, thinking or making decisions.
Sleep disturbance: difficulty getting to sleep, staying asleep or especially waking up early. Changes in appetite: usually loss of appetite but sometimes increased appetite. Weight loss or occasionally weight gain, fatigue, decreased energy, difficulty concentrating, thinking or making decisions. Symptoms of delirium: Reduced awareness of the
1.1 Explain what is meant by the term ‘dementia’. Dementia is a condition which is described by a number of symptoms and is a progressive decline of mental abilities and cognitive function as well as changes in personality, mood, communication and behaviour. Dementia is caused by chemical and structural changes within the brain as well as brain injury. 1.2 Describe the key functions of the brain that are affected by dementia. Dementia can affect the following key functions of the brain: - Temporal lobe - Parietal lobe - Frontal lobe - Occipital lobe - Hippocampus - Cerebrum lobe These all affect the function of: -Memory -Emotion -Cognitive skills -Perception -Behaviour -Communication -Senses and movement 1.3 Explain why depression, delirium and age related memory impairment may be mistaken for dementia.

Hippocampus is responsible for memory forming, organizing and storing and emotions 1.3 explain why depression, delirium and age-related memory impairment may be mistaken for dementia Depression can be mistaken for dementia because when someone is very depressed their memory can be affected. Symptons of depression: Anxiety, irritability, Delusions Hallucinations Increased or decreased body movements Pacing, wringing their hands, pulling or rubbing their hair, body, or clothing Sleep disturbance: difficulty getting to sleep, staying asleep or especially waking up early Changes in appetite: usually loss of appetite but sometimes increased appetite Weight loss or occasionally weight gain Fatigue, decreased energy Difficulty concentrating, thinking or making decisions Slowed speech, slowed responses with pauses before answering, decreased amounts of speech, low or monotonous tones
Dementia Awareness Unit 237 Dementia is a condition which is the gradual loss of brain function, this also makes it degenerative. It can include symptoms such as memory loss, confusion, problems with speech and understanding. Dementia at the moment has no cure, as it has a number of diseases that coincide with it. Alzheimer’s is part of dementia. Functions that are affected by dementia are; Short term Memory loss, Language skills, the ability to interpret information, spatial skills, judgement and attention.
For example, a victim in an accident resulting in head injury may have difficulty remembering anything new. Concussions are a leading cause to anterograde amnesia. It is also a very common type amongst elderly people battling for of dementia, such as Alzheimer’s. In cases of anterograde amnesia, the damage resides in areas of the hippocampus,
Unit: Dementia Awareness This unit must be assessed in accordance with Skills for Care and Development’s Assessment Principles. Learning Outcome 1: Understand what dementia is Assessment Criteria 1.1. Explain what is meant by the term ‘dementia’ Dementia is a term used to describe a range of signs and symptoms that occur when the brain is affected. Chemical and structural changes in the brain damage and kill brain cells, dementia is a progressive disease and this simply means that the symptoms will gradually get worse. Neurons and synapses become damaged by dementia they may be unable to carry messages that tell a section of the brain what to do.
At the other end of the age spectrum, elderly individuals often confront problems with health issues or medications that trigger sleep deprivation. For these unfortunate people, sleep deprivation may aggravate existing health conditions or create new problems. Lack of sleep may also produce confusion, distortion of memory, or depression. For aging persons, a sleep deficit may also have physical ramifications. Decreased muscle strength, increased deterioration of vital organs and an intensified reaction to pain are commonly observed in elderly people who do not get sufficient sleep.
Dementia Awareness Understand what dementia is. 1) Dementia is where there is a decline of the brain and its abilities, it is caused when the brain is damaged by disease, for example, Alzheimer’s disease, damage to the brain or a series of strokes. There are several types of dementia these include, vascular, Alzheimer’s, lewy bodies, fronto-temporal. 2) Areas affected by dementia are memory loss, speed of thinking, mental agility, language, understanding and judgement. 3) Other conditions such as depression and delirium both have similar symptoms as dementia.
People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving. However, there is a major difference in the two diseases. Alzheimer’s disease tends to affect the whole of the brain and to progress gradually and steadily. Vascular dementia tends to affect only certain areas of the brain, and this means someone may retain more of their abilities – and also more awareness of their condition. Dementia syndrome or ‘mixed dementia’are terms for a condition in which abnormalities characteristic of more than one type of dementia occur simultaneously in the brain.
